IMPRO'VED DEVICE FOR MOULDING- SOLES OF BOOTS AND SHQES.

The Schedule referred jo in these Letters Patent: nd making part of the same Be it known that I, S. D. TRIPP, of Lynn, in the county of Essex, and State of Massachusetts, have invented a new and useful Improvement in Presses for Moulding Boot and Shoe-Soles; and I do hereby declare that the following is a fnll,.clcar, and exact description thereof, which lwill enableiothers skilled in the art to make and use the same, reference being" had to the accompanying drawing, forming part ot' this specification. v

This invention relates to a machine for moulding or forming the soles of boots and shoes, so that they shall correspond with the'last, and consists'in producing the pressure by means ot' a roller, revolved between two inclined planesby abent lever, and in the construction, arrangement, and combination of parts, as hereinafter more fully described.

In the accompanying plate of drawings- :Figure l represents a sectional elevation ofthe machine on the line x x of fig. 2.

Figure 2 is a horizontal section on the line y y of fig. 1.

Similar letters of' reference indicate corresponding parts.

A A represent two stands, which rest upon' the floor, and form the main support of the machine.

They are connected together hy the rigid bed-piece B and by the adjustable cap-piece C.l

D is a cross-head, which slides freely up and down on the stands A A.

One half the mould is attached to the under side of the cap C, and the other half is attached to the upper side of the cross-head I).

The cap C being iixed, the moulding or forming of the leather sole is accomplished by forcing up the cross-head l).

'lhe upper Aside of' the bed-piece B is an inclined plane.

E is the presser-bar, the foot E of which is also an inclined plane, corresponding in form wit-h that on B, but placed in a reverse position.

G is the roller between the two inclined planes. The roll is kept in its proper position by a groove in its periphery, and by ribs on the inclined planes, as Seen iu the drawing.

v Il is a bent or clbow-foot lever, whosefulcrurn is at I, on the curved legs J J.

lhe :.rm K of the lever is connected with the foot of the presser-bar by the rod L, and thc press is actnatcd by bearing upon the foot-piece M oi' the lever, which throws forward. the foot of the presser-bar, and revolves the roll between the inclined plaines.

The presser-bar is raised by the inclined planes, as it is thrown iin-ward, and imparts the movement to the cross-head l) and mould thereon.

N is an arm, rigidly attached to the curved legs J.

0 is a spiral spring, attached toNand to the presser-bar, the duty of which, is by its recoil, to draw back the foot ot' the presser-bar, and thereby lower the cross-head and lnould, as it is ,represented in the drawing.:` y

By this arrangement almost any amount of power maytbe imparted to the cross-head, and consequently, the soles of boots and shoes subjected to the pressure between the parts of the mould, not only assume the shape or form of the mould, butthe leather will be condensed and rendered hard and firm.I

By means ofthe inclined planes and roller, arranged as seen, by a very slight application ofpower to .the lever-H, the desire'd result is obtained, thereby saving a vast amount of time and labor in bootv and shoe- -man ufhotories.

2. In combinatiln with lever AE F, bed B, and trav# eller G, the elbow-lever H K, strap L, spring O, and bar N, all arranged, as described, to form a train of mechanism through which foot-power can be applied, as set forth.
